Dehumidifier or humidifier vibrates excessively and may move on the floor.

Safety: Unplug before inspection.

Steps:

• Level the unit: Place the appliance on a flat, solid surface. Adjust feet if provided.
• Inspect fan wheel: Check for broken or missing blades and ensure the wheel is centered on the shaft.
• Tighten mounts: Verify that the fan motor and compressor mounting screws are tight.
• Replace damaged fan: If the fan wheel is cracked or badly imbalanced, replace it with a new Trotec fan wheel.
